Giving my broody eggs today!

I have set up a small pen in the run, and put a small plastic dog house in it for her to set in. Should I put something over the front of the dog house to keep it darker and help her feel more hidden. I was thinking a small peice of plywood. She is a med. size BO, does 8-10 eggs sound about right?

You haven't moved her yet correct? I wouldn't think the plywood would be necessary, but I would wait a day or so after moving her before giving her the eggs. She's liable to fuss a bit and be restless when you first move her and you don't want eggs to get broken in the process.
